我对 Julia 还是很陌生，正在努力寻找一些小事来帮助我学习，但我目前陷入困境。我想使用 Selenium 在 Julia 中创建一个网络爬虫。WebDriver.jl似乎没有更新为与 Julia 1.0+ 一起使用，并且我尝试使用 PyCall 受到错误的阻碍。

我的代码目前看起来像这样：

using PyCall
@pyimport selenium
@pyimport selenium.webdriver as webdriver

profile = webdriver.FirefoxProfile()

profile[:set_preference]("browser.download.folderList", 2)
profile[:set_preference]("browser.download.manager.showWhenStarting", false)
profile[:set_preference]("browser.download.dir", cd())
profile[:set_preference]("browser.helperApps.neverAsk.saveToDisk",
                          "text/plain,text/x-csv,text/csv,application/vnd.ms-excel,application/csv,application/x-csv,text/csv,text/comma-separated-values,text/x-comma-separated-values,text/tab-separated-values,application/pdf")

options = webdriver.FirefoxOptions()

options[:set_headless](headless=false)

driver = webdriver.Firefox(firefox_profile=profile, options=options, executable_path="/home/mcamp/PythonProjects/BudgetApp/geckodriver")

最后一行给出了这个错误：

ERROR: PyError ($(Expr(:escape, :(ccall(#= /home/mcamp/.julia/packages/PyCall/0jMpb/src/pyfncall.jl:44 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class 'selenium.common.exceptions.SessionNotCreatedException'>

firefox_profile通过排除和 ，我可以让 Firefox 启动并做一些简单的事情options。我认为正在发生的事情是，我正在尝试将 Python 对象传递给该方法，而 Julia 可能围绕它进行了变异，因此 Python 不确定如何处理它。

TIA
